[LLVMdev] Generating DWARF information that pretends an outparam is the return value
The Rust compiler defines all functions as returning void, with the
first parameter being an outparam of the declared return type, ie.
fn foo2() -> int { ret 5; }
becomes
define void @_ZN4foo217_5cb557d30658848cE(i64*, { i64, { %tydesc*, i1,
{} } }*) uwtable {
store i64 5, i64* %0
ret void
}
I'm working on generating debug information for Rust, and I'm
currently stumped on how
